Tax Accounting refers to accounting for the tax related matters. It is governed by the tax rules prescribed by the tax laws of a jurisdiction. Often these rules are different from the rules that govern the preparation of financial statements for public use (i.e. GAAP). Tax accountants therefore adjust the financial statements prepared under financial accounting principles to account for the differences with rules prescribed by the tax laws. Information is then used by tax professionals to estimate tax liability of a company and for tax planning purposes.
